The user wants me to consolidate all the notes into ONE comprehensive Markdown note that represents the current best statement of what is established about whether US universities grow or shrink due to AI over the next 20 years, with regional dependence.

Format:
- # title (the claim in one line)
- Short paragraphs
- End with: "What would change this: …"
- Keep sources or Unverified: tags
- Don't mention tools, sessions, or that I'm revising
- Keep every claim that still holds, drop repetition, sharpen wording

Let me compile the full durable claims inventory from all the notes (especially Note 14's comprehensive inventory, Note 7's inventory, and Note 16's additions):

**Core answer:**
- "Both" — the system bifurcates and thins; region- and stratum-specific. It doesn't shrink uniformly, and it doesn't grow uniformly.
- Total enrollment drifts ~19M → ~14–15M by 2045 (Unverified)
- Degrees conferred roughly steady while institution count falls — "thins, doesn't shrink"
- Median campus roughly halves in enrollment (this is aggressive; I'll keep as a mid-tier claim)
- AI is an accelerant/sorter of existing trends, not the primary cause
- Two-front squeeze: fewer 18-year-olds AND weakened degree signal

**Demography (sourced):**
- Births 4.32M (2007) → ~3.59M (2023), ~17% decline (CDC/NCHS)
- HS grads peak ~3.9M/yr ~2025 (WICHE "Knocking at the College Door")
- Birth dearth hits college age 2029–2037
- NE/Midwest/Plains lose 10–20% college-age cohorts (WICHE); TX/FL/TN/GA/Carolinas grow
- Net domestic migration to Sun Belt (Census Bureau)
- WICHE ~13% decline in HS grads by 2041

**Credential value / signaling:**
- Screening vs insurance decomposition: screening dies first (AI-verified work samples cheaper than proxy-filtering); insurance (blame-shifting/liability cover) is sticky residue, persists in regulated/litigation-exposed sectors through 2040s
- Post-2035 degree demand tracks a sector's legal/liability regime before it tracks region
- Licensed/statute-gated fields hold (nursing, law, accounting, teaching, engineering, medicine); super-selectives hold
- Mid-tier unlicensed BA premiums compress 30–50% real by mid-2030s (Unverified)
- Fastest collapse in generalist white-collar fields (business, communications, generic liberal arts)
- By ~2035 median degree = positional luxury marker; degree reprices from entry ticket to exit credential
- "AI doesn't kill the degree; it kills the undifferentiated degree"
- Credential-value decay hits by major before by institution — compositional churn
- Pre-AI drift evidence: Burning Glass Institute "The Emerging Degree Reset" (~46% of middle-skill postings dropped degree requirements 2021–22); HBS "Dismissed by Degrees"
- Stanford Digital Economy Lab "Canaries in the Coal Mine" (2025) — early-career employment declines in AI-exposed occupations
- Total degree-seeking enrollment falls 15–25% below demographic baseline by 2045 (Unverified)
- Mid-market enrollment contracts 25–40% by ~2035 (Unverified)
- Micro-credentials are a middle-market illusion — complement at top, fail to stabilize bottom
- Two brakes: AI application floods push employers back to crude degree filters; elite alumni networks
- Elite degrees gain value BECAUSE verification makes mid-tier signals redundant
- Degree survives as insurance (sorting, licensure, networks), not instruction
- Demand migrates to "protected degree + AI skill stack"
- "Bachelor's required" listings fall 30–50% in AI-exposed occupations by late 2030s (Unverified)
- Statutory gatekeeping: residual degree value set by statutory gatekeeping, not brand signal. Enrollment holds/grows where license legally requires degree + physical attestation; decays fastest where degree is pure wage-signal
- Licensure premium vs signaling premium: signaling dies, licensure survives because enforced by state boards; degree wage premium decouples by field before enrollment aggregates move
- Hiring decomposes by sector: degree requirements vanish first in at-will, project-based, reputation-portable sectors
- AI-skills training is not a university moat: demand for AI skills exists but flows to employer upskilling, short-cycle providers; universities can bolt on certificates but can't own that channel (from Note 15 analysis — the session substance claim). Reconciliation with "micro-credentials middle-market illusion": universities launching micro-credentials won't save the middle market; the demand goes to non-un
